By commenting on the nationwide commotion over Bihar Board topper Ruby's video, where she said 'Political Science' is all about 'cooking' and pronounced 'Political Science' as 'Prodigal Science', her grandfather said, "A child can get nervous for the first time in front of camera."

Her grandfather admitted that Ruby cleared the class 10 examination with a second division and did not imagine that she would get a score of 444 marks out of 500 in class 12.

Referring to Ruby's answer of "Prodigal Science", grandfather said that Ruby "got nervous" in front of camera and "got a question wrong."

"We will get to know if there is any criminal conspiracy behind such a result", said, Chief Minister Nitish Kumar.
